This unique embossing Coder, the PULSAR, can code up to 10 characters on to plastic or paper bags with great speed and efficiency. It is capable of placing one or more complete coding stamps on a bag, varying in width from 10 cm upwards and at a passage speed of up to 16.8 m/min. The embossing system utilizes coding wheels which are quickly and easily rotated to change the code. The coding head itself is “key-locked” for security.
